Hi all -

I'm relatively new to EA's and have what may be a excessively simple
question.  My oxygen tenk seems to be dropping quickly - it's gone from
2250 psi to 1400 psi in about 4 months.  I believe our previous tank
lasted much longer.  I've leak tested (with soapy tap H2O) all the
fittings that are between the oxygen tank and the EA and all the
fittings in the EA.  Does anyone have any suggestions for internal
sources of O2 loss?

Also, I noticed the metal fittings below the autosampler and above the
oxidation reactor tube are very hot to the touch.  Does anyone else
experience this?

Thank you!
